石油工业正在积极地寻求新的技术来解决一个共同的难题：降低资金消耗的同时尽量减少对环境的不良影响。由于预算减少，不少石油公司被迫采用新的策略，例如：在陆地石油边缘盆地的开发和勘探评估、老井再钻、边际油田的开采等多种情况下，利用小井眼钻井，被认为是减少费用的适宜方法。本文就降低老油区边际油田开采的钻井费用提出了总体概述。基于这种特殊构想，针对上述目的对一些相应的技术措施进行了调查。介绍了一种特别适合边际油田开发的新型钻机，同时提供了它在油田的初步使用情况 The oil industry is actively seeking new technologies to solve one common problem: reducing capital expenditures while minimizing adverse environmental impacts. Due to the reduced budget, many oil companies are forced to adopt new strategies such as drilling in slim-hole wells in many cases, such as the development and exploration assessment of terrestrial oil marginal basins, the re-drilling of old wells and the exploitation of marginal oil fields, Is a suitable way to reduce costs. This paper presents a general overview of drilling costs to reduce marginal oil fields in the old oilfield. Based on this special idea, some corresponding technical measures were investigated for the above purposes. A new type of drilling rig that is particularly suitable for the development of marginal fields is presented along with its initial use in the field
